Hi all,
I tried to compile Xenomai 2.5rc4 with uClibc 0.9.30.1 and ran into some
problems with references to the
posix functions shm_open and shm_unlink in /src/skins/posix/wrappers.c,
which do not exist in uClibc.
Unlinke in /src/skins/posix/shm.c the existence of these functions is not
verfied (via #ifdef HAVE_SHM_*)
and the build fails.
The following patch is a quick and dirty fix for this problem. I hope this
might be helpful.
